To all whom it may concern.' y

Be it known that we, .loi-iN Senasa Rrrrimr and CLYoe Pimero): VVAGNnn, citizens of the United States, residing at Joplin, in the county of Jasper and State of Missouri, have invented certain new and useful Improvements in Pair-"Cleaning lillau chilies7 of which the following is a specifica tion, reference beinghad to the accompanying drawings.

This invention relates to certain improvements in pan cleaningr machines and has relation more particularly to a machine of (this general 'character especially designed and adapted for use in connection with the flat pans generally employed in baking operatfions. p t 1s also an object of the invent-ion to provide a device of this general cnar eter having novel and improved means whereby a pan, after being` cleansed, has anplied thereto a coating of oil, such as cotton seed so that the pan is ready for use for baking when deliveredfroin the machine.

The invention consists iii the details of,

construction and in the combination and arrangenientof the several parts of our iniproved pan cleaning machine whereby certain important advantages areal/tained and the device is rendered simpler, less expensive and otherwise inore convenient and ad,- vantageous for use, all will be hereinafter more fully set forth.

The novel features oftthe invent-ion will be carefully defined in appended In order that our invention may be the better understood, we will noiv proceed to describe the same with reference to the ac conipanying drawings, wherein Figure 1 1s a longitudinal vertical section taken through the machine as herein dis closed; Fig. 2 is an enlarged fragmentary .inotefrom that shown in Fig. 2.

Asfdisclosed iii the accompanying drawings, 1 denotes a side beam with which coacts the tie` members 2 and having enacting;l

therewith the supporting` uprights 3 with which the connecting members i coact. The

supporting uprights in longitudine. nement are connected by the horizontally dis posed beams 5 positioned a predetermined distance below the beams l and in parallelism therewith. Adjacent eift'eniities of the beams l rotatably support the" shaft 7 provided in close proximity to the inner faces of the beams l with the sprockets 8 and around each of said sprockets 8 .is disposed the endless chain 9, the upper stretch of which being substantially flush with the upper longitudinal edge of the adjacent beam l. rllhe chain 9 is also directed around a sprocket l0 in longitudinal alinenient with the sprocket and alliXed to the shaft 4l1 adjustably mounted within the longitudinally disposed recess ll. produced in the end of the beam l opposite to the shaft 7. CO- acting; with the shaft ll. is the adjusting iiieniber l5 whereby it 'will be perceived that the. requisite tension niay be applied to the endless chain 9.

rlie machine as herein disclosed is particularly' adapted for use in connection with the flat pans generally employed -in baking operations in the manufacture of crackers ofthe like and the chain Sl is adapted to have-positioned there-on a pan lJ to be cleansed so as to cause the same to travel l longitudinally of the beams 1 and beneath the members to be hereinafter more particularly referred to.

Each of the beams l. at substantially its longitudinal c'eiiter provided `with the upstanding transversely aliiied bearing 17 in which is suitably mounted for Vertical atl"- justnicnt the shaft 1S having alilxed thereto .thed'iuin 19 from which substantially radiate the wire bristles :20 adapted to engage the upper surface of the pan l) to sci-ape therefrom all waste matter which may be adhering thereto, and it is to be aartcularly noted that the wire bristles 20 are irregularly lient in all directions so that the entire surface of the pan 'will be operated upon.

Uperatively engaged with the shaft l1S through the medium of the chain 26 is aV shaft '2Q having each of its-.end portions io tatably supported by a bar 29 carried by, a side beam l.' Allin-ed to the shaft 28 is the d rnin provided with the cloth windings 3l adapted to serve as a butler and contact with the pan l) for wiping;r the upper surfacethereof and thus effectively cleans the pan. The shaft 28 travels in the saine diion as the shaft i8 and at the same axial speed. f

ln order to prevent the upper stretch of latented liti? 191th.

the chain 9 vfrom sagging and thus assure a pan P to be held solid against the pressure of the bristles 20 and buffer 31, we find it of particular .advantage to dispose beneath the upper stretch lof the chain 9 the elongated metallic strip 32 secured to the brackets 33,

said brackets being secured to the inner faces of the beam l and are capable of vertical adjustment, as is indicated at 34, this adjustment permitting a convenient and effective control of the pressure on the pans when passingunder the revolving cleaning memers.

The shaft 47 has' eachend portion rotatably supported by the bearing 48 carried '.'by a beam 1 at a predetermined point rearwardly of thebearings 29. The shaft 47 has its intermediate peripheral portion reduced, as at 49, to. afford an annular charnber when Vthe cylindrical head 50 is applied to said shaft and said headtlOy is provided with the radial openings 51' 1n, communication with said compartment so'that the oil delivered within the tubuifar shaft 47 through the medium .of the feed pipe 52 may be discharged under the influence of centrifugal force upon the bristles 53 radiating from the head' 50, 'said bristles being preferably Russian hog bristles. The head 50 is adapted to have about 125 R. P. M.

` andthe oil discharged on said bristles is adapted to be spread upon the pan P so that l said'pan when taken from the machine is properly greased for a` further baking operation. As herein embodied, the delivery pipe 52 leads from a supply tank 54 operatively supported above the oiling brush by 'the brackets 55 also suitably secured to the upturned, as indicated at 59, and is provided with the pet cock 60, for purposes which are believed to be self-evident.' lVe also find it of advantage to have interposed in the supply pipe 52 intermediate the tank 54 and the shaft 47 the controlling valve 61. The

shafts 18, 28 and 47 coact with their respective bearings in a similar manner and it is therefore believed that the disclosure in Fig. 2 will. suice for each of the shafts. As particularly shown inFig. 2, it is to be cb? served that the shaft is disposed through a block 62 mounted for vertical sliding movement within the bearing and disposed at opposite sides of saidlblock are the springs 63.

l whereby7 it will be perceived that the shaft is capable of a yielding movement in order to compensate for any inequalities or unevenness of the pan passing thereunder. In practice, We find it of 'particular advantage to have the upper spring l63 of less tension than the lower spring. We alsoY find it of advantage to employ the endwiseadjustable members 64 suitably threaded'through,I *l

the bearings and engageable with the'block-l 62 to maintain the same against vertical movement when itis desired to maintain the shaft in a fixed position. The .block 62 is` also provided with the lubricating cup 65 so that the ,shaft may b e suitably lubricated. A similar mounting for,the shafts 18 and 28 permit the scraping brush and wiping brush to also have yieldable movement in i' order to compensate for any inequalities or unevenness of the pan passing thereunder. Positioned in advance of the scraping brush and in advance of the Wipinglbjl sh inl communication with a commoncond-uit 76 leading to the suction fan 77 supported by. the platform 24. The discharge spout 8l of the fan delivers within the box 82, the upper portion of which being perforated, as indicated at 83, while the lower..,part thereof is provided with the removable diawer 84. ,It will at once be perceived that the Waste material separated from the pans by the scraping brush. and wiping brush will be collected by the suction head 74 and carried within the box 82 and deposited, within the drawer- 84. We .also find' it of advantage to provide each" of the heads 74 with the iexible strip 85V preferably of canvas and which is adapted to rest upon the pan to prevent any waste matter being drawn past the head. It will also be understood that the strip 85 .possesses suff.

cient weight as to protect itself against the suction action of the fan-77. Each of the heads 74 at the ends thereof" are-provided with the depending brackets .74a suitably secured to the inner faces of the side y.

beams 1 whereby said head is fixedly main- -tained in its applied position. n

It will also be understood that the perfo l f rations 83 Within the box 82 possess an aggregate area in excess of the bore of the discharge spout 81 so that the aircan escape from the box and the waste matterldropped within the drawer 84. .The shafts 18 and 47 together with the fan 77 are adapted to afforded by the chain 26. p fFrom the foregoing description, it is iso 1215 be operated in any convenient manner and thought to be obvious that a pan cleaning A,machine constructed in accordano?I with our invention is of an extremely simple and comparatively inexpensive nature and is particularly well adapted for use by reason of the convenience and facility with which it may. be assembled, and it will also be obvious thatvour invention is susceptible of some change and modification without material departure from the principles and spirit thereof and for this' reason We do not wish to be understood as limiting ourselves to the precise arrangement and formation of the several parts herein Shown in carrying out our invention in practice.
